Domain of the equation: 2s!=0

s!=0/2

s!=0

s∈R


We add all the numbers together, and all the variables

11s+31/2s-64=0

We multiply all the terms by the denominator


11s*2s-64*2s+31=0

Wy multiply elements

22s^2-128s+31=0

a = 22; b = -128; c = +31;
Δ = b2-4ac
Δ = -1282-4·22·31
Δ = 13656
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{13656}=\sqrt{4*3414}=\sqrt{4}*\sqrt{3414}=2\sqrt{3414}$
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-128)-2\sqrt{3414}}{2*22}=\frac{128-2\sqrt{3414}}{44}
$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-128)+2\sqrt{3414}}{2*22}=\frac{128+2\sqrt{3414}}{44}
